OPTIONSAND FUTURE DISCUSSIONS

7.1 Option to License Assay. If Biocept does not obtain at least ten million dollars ($10,000,000) in equity
financing by December 31, 2012, then Life Technologies shall have the non-exclusive option, exercisable by written notice to Biocept given no later than January 15, 2013, to negotiate with Biocept for a license (unless the parties mutually
agree to a different transaction structure) to all necessary Intellectual Property

14

Rights and know-how to independently commercialize the Assay in accordance with applicable Laws. Biocept will provide notice to Life Technologies on December 31, 2012 if the conditions for
the option apply, and if Life Technologies delivers written notice of exercise of such right of negotiation to Biocept on or before January 15, 2013, the parties will negotiate in good faith to conclude a license agreement no later than
February 28, 2013. If such license has not been entered into by the parties by February 28, 2013, there are no further obligations for either party under this Section 7.1.

7.2 Option for System Development. The parties have discussed potential adaptation of the Assay to an in vitro
diagnostic format, based on a system concept that could include specially manufactured equipment, consumables and reagents that would be sold to physicians and laboratories, and linked to the informatics engine that Life
Technologies is developing. Such systems may be used to commercialize the Assay outside the USA. Biocept grants to Life Technologies a non-exclusive option, exercisable during the two (2) year period beginning on the Effective Date, to develop
plans, and negotiate with Biocept, for the co-development with Biocept of such systems for the Assay, employing or based on Biocept technologies. Such agreement is expected to include some or all of the following components: an upfront license fee,
R&D funding, development and commercial milestone payments, royalties and/or revenue sharing, and supply/sale to Life Technologies by Biocept of proprietary components and consumables.

INTELLECTUAL PROPERTY

8.1 Existing Technology. Each party acknowledges that the other party owns certain technology and
Intellectual Property Rights which have been independently developed by, or at the request of, such other party, whether prior to, during or subsequent to the Term. Except as expressly provided in this Agreement, neither this Agreement nor the
activities performed hereunder, shall give either party any rights or interest in or to the technology or Intellectual Property Rights of the other party (or of any Materials provided by such party). Each party owns, and shall continue to own, all
right, title and interest in and to its respective technology, including, without limitation, all Intellectual Property Rights relating thereto. Without limiting the generality of the foregoing, at all times during and after the Term, Biocept shall
own all rights to its CEE technology, Selector technology (if utilized) and any improvements related thereto, generated during the performance of this Agreement. Biocept and Life Technologies shall promptly notify the other in writing upon
becoming aware of any alleged or threatened third party infringement of any Intellectual Property Rights related to the Tests. Biocept shall have the right to bring and control any action or proceeding with respect to any such infringement at its
own expense and by counsel of its own choice. If Biocept elects not to bring any such action or proceeding with respect to such infringement, it shall promptly notify Life Technologies of the same and agrees to consider, in good faith a request by
Life Technologies to bring any such action or proceeding. Any agreement allowing Life Technologies to bring such action or proceeding on behalf of Biocept shall be set forth in a separate written agreement between the parties. Except as expressly
provided above, the parties shall be under no obligation to enforce any of their Intellectual Property Rights against any actual or threatened Third Party infringements.

15

8.2 Biocept Technology. Without limiting the generality of the
foregoing, Biocept owns, and Life Technologies acknowledges Biocepts ownership of, (i) the Assay and the Selector technology, and (ii) all Intellectual Property Rights in the Assay and the Selector technology, and Life Technologies
agrees that it shall not do or suffer to be done any act or thing or undertake any action anywhere that in any manner might infringe, or impair the validity, scope, or title of Biocept in the Assay, the Selector technology or Intellectual Property
Rights owned by Biocept. Nothing herein shall limit Life Technologies ability to prosecute fully any and all Intellectual Property Rights owned by Life Technologies with any patent office or related government agency or to respond fully to any
government agency inquiry with respect to its Intellectual Property Rights, products, and services.

8.3
New Technology. In the course of the activities conducted by the parties, Biocept and/or Life Technologies may conceive of inventions or discoveries or create works that constitute intellectual property and may be patentable or registerable as a
copyright or other intellectual property right (all of the foregoing, including such intellectual property rights therein, collectively, Developments). Inventorship of all inventions and discoveries, whether or not
patentable, will be determined in accordance with United States patent laws. Authorship of all copyrightable works will be determined in accordance with United States copyright laws. Subject to Section 8.2, as between the parties, Developments
will be owned consistent with such determination of inventorship or authorship. To the extent any Development owned by Life Technologies relates directly to the practice of, or constitutes an improvement to, the Assay, Life Technologies hereby
grants to Biocept, during the Term of this Agreement, and, except in the case of termination of this Agreement by Life Technologies for Biocepts uncured material breach, after expiration or termination of this Agreement, a non-exclusive,
worldwide, royalty-free, fully-paid license, including the right to sublicense, under Life Technologies Intellectual Property Rights in such Developments, solely to develop, make, have made, use, sell, have sold, offer for sale, import,
perform and provide the Assay. To the extent any Development owned by Biocept relates directly to the practice of, or constitutes an improvement to, the Assay, Biocept hereby grants to Life Technologies, during the Term of this Agreement, a
non-exclusive license under Biocepts Intellectual Property Rights in such Development, solely to promote the Assay in the Territory and to perform the Professional Component of the Assay sold by the parties in the Territory, in accordance with
the terms of this Agreement.

8.4 Technology Licenses. To the extent that any Third Party Intellectual
Property Rights related to the capture and detection of CTCs must be licensed to perform the Assay, such royalty shall be paid by Biocept. To the extent that either party owns Intellectual Property Rights to specific biomarkers, targets, kits, dyes
or technology utilized in the Assay other than for the capture and detection of CTCs, it will, to the extent it is able, grant during the Term of the Agreement, a non-exclusive license to the other party to practice these Intellectual Property
Rights for the Assay. To the extent that either party has licensed or will license Intellectual Property Rights from Third Parties related to specific biomarkers, targets, kits, dyes or technology utilized in the Assay other than for the capture and
detection of CTCs, it will, to the extent it is able, grant, during the Term of the Agreement, a non-exclusive license to the other party, or ensure that the

16

other party is covered under its license, to practice these Intellectual Property Rights for the Assay. In the event of the foregoing, then, subject to Section 8.5, the parties agree to
negotiate in good faith an allocation of expenses for such Third Party licenses directly associated with the Assay.

8.5 Infringement.If any Third Party claims or brings an action alleging that performance of the Assay or Test by Biocept or Life Technologies or their Affiliates under this Agreement
infringe (directly or indirectly) any of such Third Partys patent rights, Biocept shall use commercially reasonable efforts to address such claims. If Biocept determines to seek a license or otherwise obtain the right to use such Third Party
intellectual property rights on behalf of Biocept and Life Technologies, then (i) if the Third Party intellectual property rights relate to the capture and detection of CTCs or the Phase I Assay analytes, then Biocept shall bear the costs of
such licenses, including the payment of licensing fees, royalties or other payments, or (ii) if the Third Party intellectual property rights relate to specific biomarkers, targets, kits, dyes or technologies for the Phase II Assay, then the
parties agree to negotiate in good faith an allocation of costs for such licenses, including payment of licensing fees, royalties or other payments that may be due to such Third Party, unless the parties agree otherwise in writing. If Biocept and
Life Technologies determine to seek a license or otherwise obtain rights to use Third Party intellectual property rights for any Collaboration Assay(s), the parties similarly agree to negotiate in good faith an allocation of costs for such licenses,
including payment of licensing fees, royalties or other payments that may be due to such Third Party, unless the parties agree otherwise in writing.

8.6 Data and Results. All data and results from performance of a Test on samples provided by Life Technologies shall be used by the parties solely to the extent necessary to perform its obligations
under this Agreement and in accordance with Section 3.5(d).

8.7 Trademarks.

(a) Biocept shall be responsible for and bear the expense of any filing, prosecution, maintenance and enforcement of the
Biocept Trademarks as it may determine in its sole discretion, without obligation. Life Technologies shall not, during the Term or thereafter, use or seek to register the trademarks or any trademark or trade name similar to or confusing with the
Biocept Trademarks, or any translation thereof, in any jurisdiction. Life Technologies agrees that, if Life Technologies at any time obtains, in any jurisdiction, any right, title or interest in any mark, symbol or phrase which shall be identical
to, similar to or likely to be confused with any Biocept Trademark or any translation thereof, then Life Technologies shall have acted or shall act as an agent and for the benefit of Biocept for the limited purpose of obtaining such registrations
and assigning such registration (and all right, title and interest in such mark, symbol or phrase) to Biocept.

(b) Life Technologies shall be responsible for and bear the expense of any filing, prosecution, maintenance and
enforcement of the Life Technologies Trademarks as it may determine in its sole discretion, without obligation. Biocept shall

17

not, during the Term or thereafter, use or seek to register the trademarks or any trademark or trade name similar to or confusing with the Life Technologies Trademarks, or any translation
thereof, in any jurisdiction. Biocept agrees that, if Biocept at any time obtains, in any jurisdiction, any right, title or interest in any mark, symbol or phrase which shall be identical to, similar to or likely to be confused with any Life
Technologies Trademark or any translation thereof, then Biocept shall have acted or shall act as an agent and for the benefit of Life Technologies for the limited purpose of obtaining such registrations and assigning such registration (and all
right, title and interest in such mark, symbol or phrase) to Life Technologies.
